BINDING ATTACHMENT FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented A11 28, 1917.

Application filed. May 11, 1915. Serial No. 27,318.

To all whom it may concern:

Be it known that I, FREDERICK T. Newron'r, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Binding Attachments for Sewing- Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in binding attachments for sewing machines and has for its object to improve that class of devices represented by United States patent to W. Pretty, Jr., No. 273,602, dated March 6, 1893.

In the use of binders of the character herein referred to it frequently is desirable to direct the binding about the free edge of the fabric so as to give to the binding a width at one side greater than at the oppo site side, instead of effecting like widths at the opposite sides as is commonly practised, and to adapt a given binder-head to the requirements of both designs of product, is the purpose of the present invention.

In the accompanying drawings, which form a part of the specification, Figures 1, 2 and 8 are views in front side and front end elevation and plan view, respectively, of a binder-head comprising the present invention, Figs. 4 and 5 views in perspective of the concaved braid-guiding member and the adjust-ably secured braid-guiding bracket, respectively, Fig. 6 an under side view of the convex braidguiding member, Fig. 7 a perspective of the concaved and convexed braid guiding-members assembled to receive the braid, Fig. 8 a view illustrating the upper and under free edges of the braid arranged equi-distant from the edge of the fabric and Fig. 9 a view similar to Fig. 8 illustrating the free edges of the braid arranged at different distances from the edge of the fabric.

Referring to the figures, 1 represents the conveXed braid-guiding member provided with the braid-guiding surface 2, walls 8 and 4 along which track the free edges of the braid, obliquely arranged delivery end 5 provided with a guide-wall 6 arranged at a right-angle to the surface 2 and an extended portion 7 provided with openings, as 8, through which pass the screws, as 9,

threaded into the base-plate 10, the delivery end of the guide-wall 4: being inclined at 11, and the delivery end of the wall 3 arranged slightly nearer the transversely arranged guide-wall 6 than the delivery end of the wall 4, for a purpose later to be explained.

12 represents the concaved braid-guiding member suitably secured upon the convexed member 1 and spaced from the surface 2 of the latter to permit of the passage of the braid l3. 1% denotes an adjustably secured braid-shifting bracket provided with a stop lug 15, braid-guard 16 and braid-shifting lug 17, a screw 18 threaded into the opening 19 of the member 1 acting to adjustably secure said braid-shifting lug with respect to the delivery end of the binder-head to elfect the desired operation, the binder-head comprising the elements as assembled in Fig. 7 less the opening 19.

Having set forth the details in construction the following relative adjustment and cooperation of the parts will be readily understood.

To effect the binding operation represented by Fig. 8 the braid-shifting bracket 14 is positioned as in Figs. 1 and 3 with its lug 17 at its limit of adjustment away from the delivery end of the binder-head, when the braid is led from the supply through the circular opening 20 to said delivery end where it is guided transversely to the length of the binder-head with its curved central portion 21 in engagement with the guide wall 6, and its folded portion beneath one form of commonly employed presserfoot and in engagement with one form of commonly employed feeding mechanism, when the machine is put in operation ai 1d the braid laid and stitched.

In eifecting the previously described binding operation the differences in the length of the wall 3 with respect to the wall a at the delivery end of the binder-head is caused to effect the product represented by Fig. 8 by the edge 23 of the binding passing over the free edge of the braid-guard 16 and in guiding relationship with the inner wall of the braid-shifting lug 17, thus arranging the free edges 23 and 24: of the braid in vertical alinement as the braid is fed to the action of the needle, and with the edge 24 out of guiding relationship with the inclined portion 11 of the guide-wall 4, all for a par 25 of the braid to overlie the fabric a greater distance than the upper fold 26, the degree of adjustment given the braid-shifting bracket acting to control the relative ar rangement of the free edges of the braid with respect to the free edge of the fabric being bound.

Having thus set forth the nature of the invention, what I claim herein is 1. In a binding attachment for sewing machines, the combination with a binder head arranged at right angles to the line of feed, inclined at its delivery end to invert a braid after it has been folded, and having edge guiding walls extending longitudinally of said binder'head, one of said edge guiding walls being straight, and the other adjacent the inverting edge of the binder, be-

ing inclined in a direction away from the curved central portion of the binder head, of adjustable means located adjacent the delivery end of the binder and engaging one edge of the braid after it has been inverted whereby the braid may be applied with equal or unequal faces upon opposite sides.

of a body fabric.

2. In a binding attachment for sewing machines, the combination with a binder head arranged at right angles to the line of feed, inclined at its delivery end to invert a braid after it has been folded, and having edge guiding walls extending longitudinally of said binder head, one of said edge guiding walls being straight, and the other adjacent the inverting edge of the binder, being inclined in a direction away from the curved central portion of the binder head, of a braid shifting bracket provided with abraid-guard and a braid shifting lug, the latter located adjacent the delivery end of the binder and engaging one edge of the braid after it has been inverted whereby the braid may be applied with equal or unequal faces upon opposite sides of a body fabric.

3. In a binding attachment for sewing machines, the combination with a binder head arranged at right angles to the line of feed, inclined at its delivery end to invert a braid after it has been folded, and having edge guiding walls extending longitudinally of said binder head, one of said edge guiding walls being straight, and the other adjacent the inverting edge of the binder, being inclined in a direction away from the curved central portion of the binder head, of a braid shifting bracket provided with a braid shifting lug located ad,- jacent the delivery end of the binder and engaging one edge of the braid after it has been inverted whereby the braid may be applied with equal or unequal faces upon opposite sides of a body fabric.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
